I find a scale the easiest weigh. Syringes are the bane of DIY.
I agree 100% first started DIY using pipettes and syringes, what a pain! Syringes can be hard to read exactly, different syringe for EVERYTHING, and then all the cleanup....I bought some good squeeze bottles, put the PG and VG in that, put some NIC(100MG per ML VG based) in a 120ml dropper bottle...Most of my containers the flavors come in I can just drip/squeeze the flavors in... some(flavors) I need to use a pipette(4 oz bottles that just have a cap). Still, put the bottle on the scale, drip,pour,squeeze until you get the desired weight, tare the scale, and then move on to the next....when I'm done, most times nothing to clean at all! VG with a pipette, or syringe , UGH... PITA, even with a large gauge needle(14-16).
So, why DIY... Once you get past the initial investment, scale, bottles, etc...the ejuice costs something like .75 to 1.75 per 30ml depending on flavors....less than $5.00 for 120ml....It's fun and I actually enjoy doing it, I know exactly what's in the ejuice, and I know where and how it's made.... All good things....
But yeah, no downside, besides learning, and the initial investment, which you back QUCKLY... Even CHEAP juice costs $15 per 120ML.....I go through about 500ml-600ml a month(maybe even more)... So buying inexpensive commercial ejuice at a cost of $15.00, per 120ML that's $75+ per month, it costs me about $20-$25.....
I could be wrong, but I've never had commercial inexpensive ejuice that was really good, some was ok, but not great. Mine is USUALLY better. Although I've made some nasty stuff too(usually when substituting ingredients). That said, I've ALWAYS been able to fix it, re-mix it, as I KNEW exactly what was in it!
My biggest piece of advice...When you buy your first flavors, have recipes already that you want to make, and that you are pretty sure you are going to like! Then BUY the exact flavors and BRANDS to make those recipes. There are many brands, and many types of the same flavors, substituting usually doesn't work out well! Example -->
Strawberry --> TFA -- Strawberry, Ripe Strawberry
Banana ----> TFA -- Banana Cream, DX Banana Cream, Banana Foster, DX BananFosterr, Ripe Bananna
The DX Prefix means not supposed to have '
Acetoin' , 'Acetyl Propionyl', etc.....
Also, you usually can't just substitute the same amounts for the DX and non-dx and expect it to taste the same.... it won't. In some case, the DX and original non-dx will never be the same....
BEST scale to buy,
American Weigh Scales LB-501 Digital Kitchen Scale
Amazon.com: American Weigh Scales LB-501 Digital Kitchen Scale: Kitchen & Dining
Currently $22.91 -- You want the 500G version, they have three different capacities listed... The 500Gram is accurate to .01 of a gram, comes with calibration weights, and an AC power cord. Power cord is NICE as scale will NOT power off, most of the scales WILL power off after 90 seconds or so. The scale also has a back light which is nice...
The 1000g might seem better for a few dollars more, BUT it's only accurate to .1g, matters when making small test batches, trust me, and 500G is enough to mix 120ml at a time, perhaps more but that's what I make...
